Phase transitions of β-ZnTe(en)0.5 under hydrostatic pressure
Data files
Abstract
This dataset contains IR spectra of β-ZnTe(en)0.5, a novel material that consists of alternating layers of two-monolayer-thick zinc telluride (ZnTe) and ethylenediamine (en). Using X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy, this study investigated the structural response of β-ZnTe(en)0.5 to applied hydrostatic pressure. Pressure-induced phase transitions were observed at 2.1 GPa and 3.3 GPa. IR spectroscopy revealed abrupt changes in NH2 and CH2 vibrational modes corresponding to the phase transitions.

Description of the data and file structure
Figures 4 and 5 are IR transmission spectra of ZnTe(en)0.5 under pressure. Due to a software error, the x axes of the IR spectra plots in the paper were shifted by +3 cm-1. Because the plots cover a broad range, this small shift was not discernible in the published figures. The data presented here have the correct cm-1 values.
